Understanding your email health results
MX Records
MX (Mail Exchange) records tell other mail servers where to deliver email for your domain. Without them, nobody can send you email. Multiple MX records with different priorities provide redundancy — if the primary server is down, email is delivered to the backup.
SPF Record
SPF (Sender Policy Framework) specifies which mail servers are allowed to send email on behalf of your domain. Without it, spammers can forge your domain in the "From" address, and your legitimate emails are more likely to land in spam folders.
A proper SPF record looks like: v=spf1 include:... ~all
DMARC Record
DMARC tells receiving mail servers what to do when an email fails SPF or DKIM checks. A policy of p=none just monitors, p=quarantine sends failures to spam, and p=reject blocks them entirely.
Without DMARC, your domain is fully open to spoofing — anyone can send email pretending to be from your company.
DKIM & Blacklists
DKIM (DomainKeys Identified Mail) adds a cryptographic signature to outgoing emails so recipients can verify they genuinely came from your server and weren't tampered with in transit.
Blacklists are databases of IP addresses and domains known to send spam. If your mail server's IP is listed, your emails may be blocked or filtered by recipients before they're even read.
